Timing a passage to Tahiti around a closing weather window

With a cousin flying in five days out, Lauren Landers Sailing identified the current day as the last viable window to reach Tahiti before conditions deteriorated. After that point, the swell was forecast to reach four metres and the wind would be straight on the nose. The passage was also needed for practical reasons: dropping off donations, disposing of trash, doing an oil change, and fuelling up. Two welders had already cancelled on her for davit repair work, so that project would have to wait, but the maintenance tasks in Tahiti could not.
